AMSOIL Upper Cylinder Lubricant

AMSOIL Upper Cylinder Lubricant (UCL) is the latest addition to the gasoline additive lineup and available at Haldimand Synthetic Oil. It delivers more lubricity than the competition and battles ethanol-related corrosion.

Why Do I Need an Upper Cylinder Lubricant?

Upper cylinders are one of the toughest areas of an engine to lubricate due to the intense heat of combustion and the design of today’s vehicles. New AMSOIL Upper Cylinder Lubricant delivers a much-needed layer of protection to this trouble area to help fight piston-ring and cylinder wear, maximizing engine compression and horsepower. Its lubricity improvers aid in protecting fuel injectors and other fuel-system components from wear, helping ensure excellent performance and long life.

Unlike competing fuel additives, AMSOIL Upper Cylinder Lubricant really works. It delivers 18 percent more lubricity than Lucas* and 20 percent more than Sea Foam* for better retention of horsepower and fuel economy.[1]

Inhibits Ethanol Related Corrosion

Upper Cylinder Lubricant uses potent corrosion inhibitors to coat metal surfaces, block out moisture and stop deterioration before it starts. This is particularly important when using gasoline that contains ethanol due to its propensity to attract water and hasten corrosion. Inhibiting corrosion maximizes component life and reduces wear in the engine’s top-end to guard against compression loss and maintain optimum power.

Detergent Additives Keeps Injectors Clean

Upper Cylinder Lubricant contains detergent additives designed to maintain injector cleanliness. It’s designed to work in concert with AMSOIL P.i. Performance Improver (API) to maintain injector and combustion-chamber cleanliness, retain fuel-economy and performance gains and maximize component life.

Capless Fuel System Compatible

The AMSOIL Upper Cylinder Lubricant bottle is fully compatible with capless fuel systems. Many new vehicles have replaced traditional fuel caps with capless systems. The threads on most bottles restrict them from opening the flap inside the fuel neck and also make removing the bottle difficult. Our packaging makes it easy to insert, pour and remove the bottle.

Use Recommendations

• For use with cars and trucks.
• For best results, use with every tank of fuel. Do not refill tank until almost empty.
• Treats up to 25 gallons. Add entire bottle to tank at fill-up.
• Treat large gas tanks with two bottles of Upper Cylinder Lubricant. Using more than two bottles is not recommended.
• Safe for use with catalytic converters, oxygenated gas and up to 15 percent ethanol-blended fuels. Do not use with E85 fuel.
• Do not use with two-stroke or diesel engines.

2019 Durango 5.7 - Upper Cylinder Lubricant

I'm on my 2nd tank in my 2019 Durango 5.7. I usually use fuel that has about 10 to 15% ethanol. I've already noticed the Injector noise that's so common on all hemi engines is totally gone.
